[1.0.3] - 2026-07-21

Fixed

• Analysis env provisioning is parso-version-aware (Fix issue 105: Removed unused parameter issue #105 #107): on hosts whose default
  python3 is newer than the newest grammar the installed parso ships (e.g. Python 3.14
  with parso ≤ 0.8.4), every file failed jedi parsing and the run completed "successfully"
  with an empty symbol table. Provisioning now derives parso's supported ceiling at runtime
  from its shipped grammar files and prefers the newest supported interpreter on the host
  (versioned PATH names, then pyenv installs), falling back loudly only when none exists;
  an explicit SYSTEM_PYTHON is still honored, with a warning when unsupported. A run in
  which every discovered file fails now logs a prominent error instead of staying silent,
  and parso>=0.8.5 (the first release with the 3.14 grammar) is a direct dependency.
